It is believed that more than three inches could again fall as snow spreads from the southwest, with blizzard conditions described as a “possibility” as winds strengthen.

However, the Met Office did say there was a “good deal of uncertainty” about the intensity of the snow and how quickly it will turn to rain, as it issued yellow alerts for the majority of the country, with amber alerts for the Midlands, the north-west and parts of Wales.

Weatherquest forecaster Phil Garner, based at the UEA, said two to three inches was possible in a 24-hour period from Friday afternoon, but agreed there was a degree of doubt about how much snow would fall.

Mr Garner said that the temperature was expected to rise afterwards but that melting snow could then be frozen at night.

“The problem will be snow on Friday and Saturday, and ice on Sunday and Monday,” he said.
